Display Switching Color Spaces via Dynamic Light Source Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional displays are limited to a single color space specification, such as sRGB, NTSC, or SMPTE, and cannot switch between them, leading to color distortion when trying to match different display and printing color spaces, making it inconvenient for users.
Innovation Solution
A display system comprising a control unit, a display unit, and a light source that can switch between multiple illumination modes, allowing the display to cover various color spaces like sRGB, NTSC, SMPTE, and PAL, using LEDs with high color saturation and a color space selection interface to avoid color distortion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a display is designed with a single color space specification, then the design is simple and stable, but it cannot switch between different color spaces causing color distortion when matching with different printing color spaces
Solution Approach 1:
The patent implements dynamic color space switching by enabling the display to change its color space characteristics in real-time based on the selected mode (sRGB, NTSC, SMPTE, or PAL). The control circuit dynamically adjusts the driving signals to the liquid crystal molecules, changing the optical properties of the display to match different color space specifications, thereby resolving the contradiction between adaptability and complexity.
Solution Approach 2:
The display system is designed with multi-functionality to support multiple color space specifications (sRGB, NTSC, SMPTE, and PAL) within a single device. By incorporating a control circuit that can select and switch between different color space modes, the display becomes universal and can adapt to various applications and printing color spaces, eliminating color distortion without requiring multiple separate displays.
2Manufacturing precision
If the display color space does not match the printer color space, then the display can maintain its native color space, but color distortion occurs in the printed output
Solution Approach 1:
The patent changes the color space parameters of the display by providing multiple predetermined color space specifications (sRGB, NTSC, SMPTE, and PAL) and enabling switching between them. When a user needs to print to a specific color space, they can select the matching color space mode on the display, thereby adjusting the display's color output parameters to match the printer's color space and eliminate color distortion.
Solution Approach 2:
The control circuit acts as an intermediary between the input signal and the display output, processing and adjusting the video signals according to the selected color space mode. It transforms the incoming signal to match the desired color space characteristics before driving the liquid crystal display, ensuring accurate color representation that can be matched to different printing color spaces.

AI summary
A display capable of displaying multi-color space and including a display unit, a control circuit, and a light source is provided. The control circuit is electrically connected to the display unit and the light source respectively. In addition, the light source is controlled by the control circuit to switch between different illumination modes, such that the display is capable of displaying multi-color space with different specifications, for example, sRGB, NTSC, SMPTE, PAL, etc.
